Answer 1

At first, they didn’t think it did exist. Paul Dirac came up with an elegant math formula 100 years ago, almost on a par with Einstein’s e= mc^2

But the formula seemed flawed because it indicated the existence of antimatter, which they thought was just science fiction.

But once again, the math came through and was proven correct all along.

Oh, and we use it every day when we get PET scans. (Positrons!)
